Long Term Evolution (LTE) mobile networks are currently deployed through the world. These LTE mobile networks make use of full packet switching and the IP protocol, unlike previous iterations of the mobile network. This change from circuit switching to packet switching allows new attacks not previously possible. Some implementations of LTE networks and mobile applications are currently vulnerable to several issues which may result in loss of privacy, incorrect billing, and data spoofing.

VoIPshield Systems Inc. has teamed up with Intel Security to deliver comprehensive solutions for Voice over Internet Protocol (VoIP) security. The announcement comes on the heels of new research that shows Internet telephony networks are a major attack vector for cyber hackers

A strategically placed firewall within your network infrastructure can help mitigate VoIP attacks. But encryption and proxy services add enhanced security. Companies have long used firewall appliances to protect and isolate their networks from internal and external security threats. And ever since Voice over IP (VoIP) emerged on the global market, security vendors have expanded their products and services to meet its demands. While attacks are more sophisticated in exploiting any weakness in a VoIP system,firewalls have progressed and become smarter in defending against VoIP attacks.

As more consumers and organizations continue to migrate from their landline to IP telephony, hackers are targeting this platform because of the sheer number of gateways that could be exploited. With VoIP, the security threat not only includes the same problems data networks face, but also issues that are specific to IP telephony. Unlike TDM phones and PBXs which had very few security issues because they are hard-wired, VoIP caller server gateways and IP phones are software based, which makes it much easier to access. Therefore protecting the infrastructure with a layered security approach is better to mitigate VoIP attacks.

Last week's cyberattack on federal government websites is raising concerns about the government's plan to switch many of its landlines over to Voice over Internet Protocol (VoIP) phones.

Voice over IP (VoIP) infrastructure has become more susceptible to cyber attacks in recent years due to the proliferation of both its use and the tools that can be used for malicious purposes. During the first quarter of 2015, our security researchers have observed a large amount of VoIP attacks worldwide; however, the majority were against UK servers.

I write about VoIP security from time to time, and it’s a prime topic for this column in a few different ways. While VoIP security is of particular relevance to TMC’s (News - Alert) audience, it’s really a small branch of the data security tree, which encompasses many strands of traffic that IT must manage over their network.

In my last post, I wrote about a current success story from a particular vendor, as it was a great example of how to work with a customer experiencing VoIP security problems and to implement an effective solution. Generally, I try to stay vendor-neutral, so I’m going to continue this topic along those lines. There are several realities related to VoIP security that don’t get attention, and SMBs in particular need to understand them. More importantly, however, they need to respond proactively, and that likely requires a change in thinking.

In my last post, I framed the VoIP security analysis around two misperceptions that allow this to become a serious issue. As a technology, VoIP is inherently not secure – it was created before broadband at a time when the hacking threats we see today did not exist. Furthermore, VoIP was outside the mainstream back then and very much built in the Internet spirit of openness and sharing. The creators were really only thinking about how VoIP would be used for good purposes rather than serving as a vehicle for cyber attackers.

Network security should always be a concern with any type of communications, especially when using Session Initiation Protocol (SIP). There are special security considerations associated with SIP trunking you should be aware of to maintain safe communications, including the threat of a brute force attack or Denial of Service (DoS) attack. Here’s what you need to know to reduce the odds of your communications becoming compromised.
